和我一起困在这里

Casting your ultimate ability grants you an aura for 2 seconds, growing in size over the duration to up to 500 units. After the duration, you taunt all enemies within the aura for 2 seconds and gain 50% damage reduction for the same duration (30 second cooldown). Additionally, gain 30 ultimate haste. Aura is activated once the ultimate's effect starts or has elapsed. On Katarina, this augment will activate at the start of Death Lotus' channel.
